Three models have been developed based on the concepts from Bass and Avolio (1989), Pearce and Gregersen (1991), McAllister (1995), West and Anderson (1996), Bock et al. (2005) and Wang and Howell (2010). Hypotheses defined in the models were examined by using a sample of 143 team members from 41 work teams at a university in Hong Kong. Group- and individual-focused transformational leadership (TFL) behaviours were found to be positively related to intention to share knowledge and team innovation. Group-focused TFL behaviour was also found to be positively related to intention to share knowledge through the mediating influence of task interdependence and positively associated with team innovation through the mediating influence of affect-based trust.
